A rotorcraft includes a fuselage, a rotor assembly, a tail section
connected to the fuselage, a propulsion system including an engine
mounted to the fuselage, and a wing mounted to the fuselage. The rotor
assembly includes a rotor having either a single or a plurality of rotor
blades which can produce a resultant force vector which can pass through
or near the center of gravity of the rotorcraft, and a spindle to connect
the rotor with a flight control assembly. The rotor assembly also
includes a tilting mast assembly having a tilting mast frame also
connected to the spindle to support the rotor. The tilting mast tilts the
rotor and provides cyclic control through a cyclic control linkage
connected to the tilting mast frame. A mast control cylinder is provided
to tilt the tilting mast assembly.
